I got no sound anymore, I thin it happend after a kernel upgrade. Pulse audio says dummy output?
I saw that there are many users that got the same problem, but all those solutions doesn’t work?
I also tried the next kernel release (using testing repos) and it fixed sound for me. So probably that will help you too, meaning they have fixed it, and it becomes available soon.
Anyway, I recommend installing LTS kernel anyway, because it is a great fallback in case of temporary kernel issues.
It happened to me also but i got it working again somehow messing around. Not sure how but i think i installed pulse audio or something and i ended up with two volume controls and got it working and then removed the one i installed. Weird!
How did you get that version back?
That version unfortunately is rather old, and not recommended, since it may easily cause other issues after updating certain other packages. So it shouldn’t be used any longer than absolutely necessary.
